Abstract
One of the efficient and effective preservation methods is the addition of
acid or silage (Hasan et al., 2001). The aim of this study was to evaluate the
differences in the stability of the silage storage of catfish waste made with the
addition of formic acid at pH 5 and pH 4.The method used in this research was
experimental, with the addition of formic acid The results of pH and NPN
analyzes were analyzed using paired T-test (paired samples test) with statistical
software (SPSS) which then saw the significance value (p). until the silage
reached pH 4 and pH 5 during storage for 21 days at room temperature. The
parameters were physical character (color and smell), pH analysis, NPN,
proximate, and amino acids. The results of pH and NPN analysis were analyzed
using a completely randomized design (CRD). The results showed that the
addition of formic acid reached pH 4 and pH 5 significantly affected the pH
stability value and the NPN value of catfish waste silage during storage at room
temperature (± 29oC). The best treatment was the addition of formic acid to pH 4
on the 0th day as seen from the analysis of NPN and proximate (protein, fat,
water, ash), with a brownish green color (does not change from the color of
catfish waste), has a sour aroma, pH value of 4, NPN 45.79%, protein 65.30 (%
dw), fat 31.21 ( % dw), water 75.80 (% gw), ash 3.49 (% dw), and total amino
acids 6.50%. Silage stability in the addition of formic acid to pH 4 and pH 5
during the storage period is relatively stable. Therefore, the addition of formic
acid to the silage of catfish waste up to pH 5 is considered more efficient, has
lower acidity so it is likely to be preferred as a feed mixture, and relatively
cheaper because it uses less formic acid.
